considering they hot fix buffed shaman heals by 20%, i think this is blizzard just not giving a shit anymore.

You mean how they buffed the 2 spells that never get used in arena (healing rain and chain heal) due to shamans being rooted to the bottom of the healing meters in PvE? They certainly did take PvP into account considering the PvErs gripes were entirely based off shamans being useless when people had to spread out for bosses so healing rain couldn't be utilized properly, yet neither of these buffs really help in those situations.

Also eathliving currently ticks for sub 6k ever 3 seconds WITHOUT battle fatigues or MS, has a relatively small chance to apply above 35% health on direct heals and is dispellable. With MS and BF you're looking at around 1k hps (after the buff) from a hot which usually isn't up when needed (as people you know, tend to burst when your cc'd or locked down) which got buffed by an amazing what.. 180health per sec? So if you leave it on for the full duration of 12 secs in pvp the buff might even give you an extra 2k health. Wootz.

Edit: Omg i forgot mastery, it might even heal for an extra 3k over 12 secs now!
